JavaScript is a programming language that makes website dynamic and interactive. With JavaScript we can create mobile apps, games, process data and much more.

JavaScript is a versatile programming language primarily used for web development. Originally created to make web pages interactive, it has evolved into a multipurpose language that can be used for both front-end and back-end development.

JavaScript enables developers to add dynamic behavior to websites, such as responding to user actions like clicks, keystrokes, and mouse movements. It’s commonly used to create interactive features like animations, form validation, and dynamic content updates without needing to reload the entire webpage.

JavaScript is a very powerful language. It can be used within any browser in the world. On top of that, it can be used to write server-side code using node.js. With the rise of frameworks like React, Angular, and Vue.js, JavaScript is also extensively used for building complex web applications with rich user interfaces. Moreover, with the introduction of Node.js, JavaScript can now be used for server-side programming, allowing developers to build entire web servers and backend services using JavaScript.

When using JavaScript inside the browser, we can change how the page looks like and how it behaves. We will only use one function to print out our results called “console.log”.

Syntax – console.log();

Example- Printing the “Hello World”; OUTPUT

console.log("Goodbye, World!"); Hello World!
